File Encryption Operation
- by kiruthika
Hi All,
I have doubt in gpg command operation .
Actually we are using gpg command for encrypting the file .
File.txt has following things.
Testing
hello world
My security things.
Now I am doing the file encryption for File.txt
gpg --symmetric File.txt
Now I got File.txt.gpg file , which is encrypted.
My doubt, if some open that file and did someone changes in that I am not able
get file content . It says my following things.
$ gpg --decrypt File.txt.gpg
gpg: no valid OpenPGP data found.
gpg: decrypt_message failed: eof
I want my file content , even though some body has done changes in that .
what should I do for this problem....?
